Scores made by a player participating in a game can be tracked by using a sensor device coupled to the player to detect when the player attempts to make a score with a ball or other projectile. When a score is made, such as when something enters a goal, it is determined whether the projectile from the player is what made the score so that the score can be properly attributed to the player or another player. Attribution can be based on whether the score occurred within an appropriate time window, which could be computed from data from the sensor device. Attribution can also be based on the use of machine readable identifiers on the projectile, player, and/or goal.

Arm sleeve for training

Inertial measurement units attached to a non-rigid body may measure a common motion event when the body changes direction of travel. Acceleration measurements made by the inertial measurement units of the event are used to determine a common reference direction which in turn can be used to derive, individually for each inertial measurement unit, a new orientation intended to be a better representation of the actual orientation of the inertial measurement unit.

System and method for calibrating inertial measurement units

A method and apparatus for accelerating a software transactional memory (STM) system is described herein. Annotation field are associated with lines of a transactional memory. An annotation field associated with a line of the transaction memory is initialized to a first value upon starting a transaction. In response to encountering a read operation in the transaction, then annotation field is checked. If the annotation field includes a first value, the read is serviced from the line of the transaction memory without having to search an additional write space. A second and third value in the annotation field potentially indicates whether a read operation missed the transactional memory or a tentative value is stored in a write space. Additionally, an additional bit in the annotation field, may be utilized to indicate whether previous read operations have been logged, allowing for subsequent redundant read logging to be reduced.

A method comprises receiving a request for generating a challenge for a device or a user of the device. The method also comprises determining location information associated with the device. The method further comprises determining one or more characteristics that are detectable based, at least in part, on the location information. Furthermore, the method comprises generating the challenge based, at least in part, the one or more characteristics.

A method for processing a video recording involves receiving sensor data from at least one sensor located on a person performing a physical activity. The sensor data includes biometric and/or biomechanical measurements taken from the person while performing the activity. The video recording is of the person performing the activity. The received video recording is correlated with the received sensor data to allow portions of the video recording to be matched with portions of the sensor data from corresponding periods of time. Correlation allows one to readily find and review video footage that show the activity being performed correctly or not based on an interpretation of the sensor data.

A method and apparatus for enabling a Software Transactional Memory (STM) with precompiled binaries is herein described. Upon encountering an access operation in a transaction, an annotation field associated with a memory location referenced by the access is checked. In response to the memory location representing a previous similar access within the transaction, the access is performed without access barriers. However, if the annotation field is in a default state representing no previous access during a pendancy of the transaction, then a mode of the processor is determined. If the processor mode is in implicit mode, an access handler/barrier is asynchronously executed. Conversely, in an explicit mode, a flag is set instead of asynchronously executing the handler. In addition, during compilation convert explicit and convert implicit instructions are inserted to intelligently convert modes for precompiled and newly compiled binaries. Furthermore, new versions of newly compiled functions may be inserted to provide strong atomicity between previously and newly compiled functions.

Methods and apparatuses are provided for facilitating sharing device connections across multiple physical and/or virtual (logical) computers. A method may include receiving a USB device request from a virtual host controller driver of a client when a host is not in a power save mode and passing a USB device request to a host controller driver of the client when the host is in a power save mode. A method may also include activating a sharing switch of a host controller to connect a device connection port to the host when the host is not in a power save mode and to connect the device connection port to the client when the host is in a power save mode. Corresponding apparatuses and computer program products are also provided.

A method and apparatus for fine-grained filtering in a hardware accelerated software transactional memory system is herein described. A data object, which may have an arbitrary size, is associated with a filter word. The filter word is in a first default state when no access, such as a read, from the data object has occurred during a pendancy of a transaction. Upon encountering a first access, such as a first read, from the data object, access barrier operations including an ephemeral/private store operation to set the filter word to a second state are performed. Upon a subsequent/redundant access, such as a second read, the access barrier operations are elided to accelerate the subsequent access, based on the filter word being set to the second state to indicate a previous access occurred.

A technique for using memory attributes to relay information to a program or other agent. More particularly, embodiments of the invention relate to using memory attribute bits to check various memory properties in an efficient manner.

Technique for using memory attributes

A method includes sending over the network from a source entity to a destination entity a sequence of a plurality of packets. Each packet in the sequence includes a same identifier corresponding to a network entity on the network. Sending includes modifying a property of the sequence of packets to uniquely identify the sequence of packets. The method includes receiving information indicating the identifier corresponds to the modification of the property. Another method includes examining a sequence of packets sent over a network from a source entity to a destination entity, each packet in the sequence comprising a same identifier corresponding to a network entity on the network. The method includes determining whether a property of the sequence of packets was modified when sent to uniquely identify the sequence of packets; and responsive to the determining, associating the identifier with the network identity. Apparatus and program products are also disclosed.

A processor includes a device providing a throttling power output signal. The throttling power output signal is used to determine when to logically throttle the power consumed by the processor. At least one core in the processor includes a pipeline having a decode pipe; and a logical power throttling unit coupled to the device to receive the output signal, and coupled to the decode pipe. Following the logical power throttling unit receiving the power throttling output signal satisfying a predetermined criterion, the logical power throttling unit causes the decode pipe to reduce an average number of instructions decoded per processor cycle without physically changing the processor cycle or any processor supply voltages.

A computer-based method configures a hardware circuit to transfer a message to a message queue in an operating system. The hardware circuit is used to transfer a message to the message queue in the operating system without requiring use of either the operating system or a hypervisor associated with the operating system. The using the hardware circuit uses a logical identifier associated with the message to select an entry in a mapping table of the hardware circuit. A value in the entry in the mapping table is used to select an entry in an action table. The entry in the action table is used to determine a tail pointer for the message queue. The hardware circuit appends the message to a location indicted by the tail pointer without requiring cycles of a hypervisor associated with the strand.
